Review: Intocircuit’s PowerMini 3000 Power Bank


You’re late for a loved one’s birthday party and after running out the door and into your car to slog through traffic, you suddenly realize the battery power on your smartphone is nearly empty. Of course, you breath a sigh of relief knowing you have a car charger, but given that you’ll be taking dozens of pictures and snippets of video, that gained hour of regular talk-time power will quickly whittle down to at most a half an hour. So, what are you going to do?

It’s a dramatic opening to the introduction of a simple solution that’s catching on among smartphone users everywhere, purse or pocket-sized portable chargers.

Intocircuit’s PowerMini 3000 Power Bank is a recent and upgraded addition in the world of portable chargers. And as you’ll discover in a moment, one that is well worth purchasing.


PowerMini 3000 Power BankThe PowerMini 3000 is a finger-sized charger that comes in either a grey or black cylindrical shaped aluminum body. The charger feels durable and all components function in a way that reflects obvious attention to detail and quality. The single end-button that enables charging is soft to the touch and sturdy enough to last a long time. Above the end-button are three LED lights that indicate charging progress that blink sequentially according to available capacity. The end-caps are plastic with the front end housing a 5V micro USB input port, a 5V USB output port and an LED flashlight. When testing this charger, it was easy to carry around, slipping easily in a pocket or a purse (I had my wife test this product using her preferred means of storage) or backpack given your preference.

So how well does the PowerMini 3000 Power Bank charge?

Using the charger is simple, just hook up your smartphone, tablet or any device that charges via USB to the PowerMini 3000 Power Bank and just press the button once. Doing so enables one of the three LED light indicators to begin flashing and viola, your device is set to charge.

I tested the PowerMini using an Apple iPhone 5c, Apple tablet mini and a Nokia Lumia 1520. Of course, the smaller the device the faster the charging rate, which always felt reasonable. It took just 2 or 3 hours to fully charge the iPhone 5C, with plenty of capacity left in the PowerMini for another charge, and just a bit longer for the Nokia Lumia 1520, although doing so sucked up nearly all of the PowerMini’s charging capacity. On larger devices such as a tablet and the 1520, the PowerMini will heat up, but this is normal for such devices and neither affected charging performance nor overheated to the point of feeling uncomfortable. If slight heating is a concern, just rest the charger on a flat, open surface to ensure exposure to cooler air. Overall, I felt the charging was fast, convenient and always reliable.

I definitely recommend the PowerMini 3000 Power Bank. Given this is my first foray into the world of portable chargers, I’ve already used it several times during a pinch. If you are a business traveler looking for an easy-to-carry charger, or a heavy user of electronic devices looking for a back-up charger, then this product is certainly for you.
